[0002] In metal processing, mold making, and profile processing, complex workpieces typically require multiple processes such as sawing and milling for finishing. Traditional production methods generally use single-function equipment, such as a standalone band saw for cutting, followed by transfer to a vertical or horizontal machining center for milling. This decentralized processing model has significant drawbacks: First, the multiple clamping and positioning of the workpiece between different machines inevitably introduces cumulative errors, severely affecting the final machining accuracy; second, the transfer, debugging, and waiting between processes consume a lot of time, resulting in low production efficiency and a low degree of automation. Utility Model Content

[0003] To address the aforementioned issues, this invention proposes a horizontal five-axis sawing and milling integrated device that combines sawing and milling functions, possesses multi-axis linkage capability, and an automatic tool changing system.

[0004] The main contents of this utility model include: a material loading module, which includes a carrier turntable and a rotary drive mechanism for driving the carrier turntable to rotate around the X-axis, and a clamping component for clamping the workpiece is provided on the carrier turntable; The processing module is located on one side of the Y-axis of the material loading module. The processing module includes a processing table, a lifting drive module that drives the processing table to move up and down along the Z-axis, an X-axis transverse drive module that drives the processing table to move laterally along the X-axis, and a Y-axis transverse drive module that drives the processing table to move laterally along the Y-axis. The processing table is provided with a processing spindle that can swing horizontally. An automatic tool changer is located on one side of the X-axis of the loading module. The automatic tool changer includes a saw magazine and a milling cutter magazine arranged opposite each other along the Y-axis. The carrier turntable can be rotated to a horizontal position for loading and unloading, and rotated to the side of the clamping assembly facing the processing module for processing the workpiece; the processing spindle can change tools by moving laterally along the X-axis to dock with the saw magazine or the milling cutter magazine.

The pressing clamping member includes a first telescopic hydraulic cylinder vertically disposed on the carrier turntable surface. The output end of the first telescopic hydraulic cylinder is connected to an L-shaped pressure rod, and the end of the L-shaped pressure rod is pressed downward onto the workpiece. Y-axis clamping unit includes a reference block and a lateral clamping member arranged opposite to each other on both sides of the Y-axis of the vehicle turntable. The lateral clamping member includes a bracket perpendicular to the surface of the vehicle turntable. A first lateral hydraulic cylinder is provided on the bracket, and the push rod end of the first lateral hydraulic cylinder is arranged toward the reference block. The bottom of the workpiece is positioned by the positioning block, the side is positioned by the reference block, and it is clamped by the first telescopic cylinder and the first lateral cylinder.

[0006] Preferably, the clamping assembly further includes a plurality of lifting cylinders disposed on the turntable surface of the carrier, wherein the push rods of the lifting cylinders are perpendicular to the turntable surface of the carrier and are used to extend after the workpiece is clamped to provide auxiliary support for the bottom of the workpiece.

[0007] Preferably, the rotary drive mechanism includes a first rotary disk and a second rotary disk connected to both sides of the turntable along the X-axis.

Detailed Implementation

[0014] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0015] like Figure 1As shown, this application proposes a horizontal five-axis sawing and milling integrated device, which mainly includes a loading module 1, a machining module 2, and an automatic tool changer 3. The loading module 1 is used for workpiece clamping and positioning, and can rotate around the X-axis to achieve multi-angle machining postures. The machining module 2 is located on one side of the Y-axis of the loading module 1 and is used to perform cutting operations such as sawing and milling. The automatic tool changer 3 is located on one side of the X-axis of the loading module 1 and includes a saw cutter magazine 31 and a milling cutter magazine 32, enabling the machining spindle to automatically change tools according to machining requirements.

[0016] like Figure 1 As shown, the loading module 1 includes a carrier turntable 11, a rotary drive mechanism, and a clamping assembly 13. The rotary drive mechanism drives the carrier turntable 11 to rotate around the X-axis. It includes a first rotating disk 121 and a second rotating disk 122 connected to both sides of the carrier turntable 11 along the X-axis. A rotary drive component 123 is connected to one side of the first rotating disk 121 to drive the first rotating disk 121 to rotate. A disc tailstock 124 is connected to the outer side of the second rotating disk 122 to provide auxiliary support and balance, thereby improving the stability and accuracy of the carrier turntable 11 during rotation. The rotary drive mechanism drives the carrier turntable 11 to rotate to a horizontal position for loading and unloading, or to rotate it to the side of the clamping assembly 13 facing the processing module 2 for processing, thus meeting the requirements for multi-angle processing of workpieces.

[0017] like Figure 1-2 As shown, the clamping assembly 13 is used to clamp the workpiece, and includes a Z-axis clamping unit 131 and a Y-axis clamping unit 132. The Z-axis clamping unit 131 includes a positioning block 1311 protruding from the end face of the carrier turntable 11 and a pressing clamping member 1312. The positioning block 1311 is used to initially position the bottom of the workpiece. The pressing clamping member 1312 includes a first telescopic hydraulic cylinder vertically arranged on the table surface of the carrier turntable 11. The output end of the first telescopic hydraulic cylinder faces upward and is connected to an L-shaped pressure rod. When the workpiece is placed on the positioning block 1311, the first telescopic hydraulic cylinder is activated, driving the end of the L-shaped pressure rod to press downward onto the upper surface of the workpiece, thereby achieving clamping of the workpiece in the Z direction. The Y-axis clamping unit 132 includes a reference block 1321 and a lateral clamping member 1322 arranged opposite to each other on both sides of the Y-axis of the carrier turntable 11. The reference block 1321 is used for initial positioning of the side of the workpiece. The lateral clamping component 1322 includes a bracket perpendicular to the surface of the carrier turntable 11. A first lateral hydraulic cylinder is mounted on the bracket, with the push rod end of the first lateral hydraulic cylinder facing the reference block 1321. When the workpiece is pressed against the reference block 1321, the first lateral hydraulic cylinder actuates, extending the push rod to push the workpiece towards and tightly adhere to the reference block 1321, achieving precise positioning and clamping of the workpiece in the Y direction. The Y-axis and Z-axis clamping units work together to form multi-directional positioning and clamping of the workpiece, effectively improving clamping accuracy and repeatability.

[0018] like Figure 1-2As shown, the clamping assembly 13 further includes several lifting cylinders 133 disposed on the table surface of the carrier turntable 11 to further enhance the stability of the workpiece during processing and prevent deformation or displacement of the workpiece due to cutting forces. The push rods of the lifting cylinders 133 are perpendicular to the table surface of the carrier turntable 11. After the workpiece is clamped in the Y and Z directions, the lifting cylinders 133 extend, and their push rods press against the bottom of the workpiece to provide auxiliary support. In a specific embodiment, the lifting cylinders 133 can be flexibly arranged according to the shape and processing position of the workpiece, which can effectively improve the rigidity of the workpiece and ensure the quality of subsequent processing.

[0019] like Figure 1 As shown, the processing module 2 includes a processing table 21, a lifting drive module 23 that drives the processing table 21 to move up and down along the Z-axis, an X-axis lateral movement drive module 24 that drives the processing table 21 to move laterally along the X-axis, and a Y-axis lateral movement drive module 25 that drives the processing table 21 to move laterally along the Y-axis. The lifting drive module 23, the X-axis lateral movement drive module 24, and the Y-axis lateral movement drive module 25 employ a servo motor-driven ball screw structure, combined with linear guides, to ensure stable movement of the processing table 21 along the Z-axis, X-axis, and Y-axis.

[0020] like Figure 1 As shown, a horizontally swinging machining spindle 22 is mounted on the machining table 21. The machining spindle 22 is driven by a built-in motor, and its swinging function is achieved through a swing mechanism (this part of the structure is existing conventional technology and will not be described in detail here). The machining spindle 22 can face different machining directions to meet machining requirements at different angles. The machining spindle 22 moves along the X and Y axes via two transverse drive modules, enabling it to precisely reach the position for tool changing with the automatic tool changer or to reach the machining area to process the workpiece. The machining spindle performs side-lying machining on the horizontal side of the workpiece. During machining, the chips generated fall naturally downwards under gravity, preventing accumulation on the workpiece surface or the carrier turntable 11, thus ensuring the cleanliness of the machined surface and the machining quality.

[0021] like Figure 3-4 As shown, the saw magazine 31 includes a magazine frame 311, a tool changer 312 mounted on the magazine frame 311, a sliding assembly 313 mounted on the tool changer 312, and a tool changer seat 314 disposed on the moving end of the sliding assembly 313. The tool changer seat 314 includes a saw blade seat 3141 connected to the sliding assembly 313 and a top-load cylinder 3142 disposed on the sliding assembly 313 and located on one side of the Y-axis of the saw blade seat 3141.

[0022] like Figure 3-4As shown, the sliding assembly 313 includes a sliding support 3131, a slide rail 3132 connecting the sliding support 3131 and the tool changer 312, and a drive mechanism 3133 for driving the sliding support 3131 to move. The drive mechanism 3133 can be a rack and pinion mechanism including a drive motor and a rack, or it can be a cylinder. The drive motor is mounted on the tool changer 312, and the gear at its output end meshes with the rack fixed on the sliding support 3131, thereby driving the sliding support 3131 and the tool changer 314 on it to move along the slide rail.

[0023] The saw holder 3141 is provided with a saw sleeve for horizontally inserting the saw blade 315. The top-cutting cylinder 3142 is arranged coaxially with the axis of the saw sleeve, and its output shaft can extend into the saw sleeve to horizontally push the saw blade out of the saw sleeve.

[0024] Tool changing process: When a saw blade needs to be changed, the machining spindle 22 moves laterally along the X-axis to a position coaxial with the saw blade magazine 31. The sliding assembly 313 drives the tool changer 314 to move towards the machining spindle 22, so that the saw blade shank is inserted into the spindle taper hole. Subsequently, the push-tool cylinder 3142 actuates, and its output shaft pushes the saw blade shank, ensuring that the saw blade and the tensioning mechanism of the machining spindle 22 are fully engaged and locked. The tool unloading process is the reverse. This structure enables rapid and automatic saw blade changing, with a smooth and reliable tool changing process and high positioning accuracy.

[0025] like Figure 5 As shown, the milling cutter magazine 32 includes a tool magazine 321, a tool changing arm 322, and a telescopic rotary cylinder 323 connected to the tool changing arm 322. The structure of the tool magazine 321 is similar to that of common disc-type or chain-type tool magazines, and will not be described in detail here. The tool changing arm 322 has arc-shaped grooves 324 at both ends for engaging milling cutter shanks. Specific details of the tool changing arm's structure are prior art and will not be described in detail here. When the machining spindle 22 needs to change the milling cutter, the spindle moves to the tool changing position. The tool changing arm 322 rotates under the drive of the telescopic rotary cylinder 323, removing the existing milling cutter from the spindle and placing it back into the tool magazine, and then grabbing a new milling cutter from the tool magazine and installing it onto the spindle. The milling cutter magazine 32 is located on one side of the X-axis of the machining module 2, with a reasonable structural layout that does not interfere with the saw magazine. The milling cutter can be returned to the milling cutter magazine before switching to the saw magazine.

[0026] Working principle: The carrier turntable 11 rotates to a horizontal position, and the operator or robot places the workpiece on the positioning block 1311 and the reference block 1321. Subsequently, the downward clamping member 1312, the lateral clamping member 1322, and the lifting cylinder 133 act sequentially to reliably clamp the workpiece. The carrier turntable 11 rotates to a machining posture (such as vertical or inclined). According to the instructions, the machining module 2 drives the machining spindle 22 to the automatic tool changer 3 to change tools (sawing cutter or milling cutter), and then moves to the machining area to perform precision machining on the workpiece in conjunction with multi-axis linkage. During the machining of the same workpiece, if it is necessary to switch processes, the machining spindle 22 can automatically return to the tool change position, and the automatic tool changer 3 can complete the replacement of the saw cutter and the milling cutter, realizing integrated sawing and milling machining. After machining is completed, the carrier turntable 11 returns to a horizontal position, the clamping assembly 13 is released, and the finished workpiece is taken out.
